Preheat oven to 375F. Line baking sheet with parchment paper or a silpat. Spray if using parchment to prevent sticking.

Combine flour, baking powder, and salt in a medium bowl. Mix well. Add yogurt and stir until crumbly.

Dust work surface with flour. Transfer dough, knead lightly until tacky but not sticky, about 15 turns.

Divide dough into 4 balls. Roll each into 3/4-inch ropes and connect ends to form bagels.

Brush with egg white. Bake on prepared sheet for 25 minutes. Cool for 15 minutes before serving.
